Energy accounting is a system used in energy management systems where measuring and analyzing energy consumption is done to improve energy efficiency within an organization.[3] Organisations such as Intel corporation use these systems to track their energy usage.[4]

Various energy transformations are possible. An energy balance can be used to track energy through a system. This becomes a useful tool for determining resource use and environmental impacts. How much energy is needed at each point in a system and in what form that energy is, can be measured. An accounting system keeps track of energy in, energy out, and non-useful energy versus work done, and transformations within a system. Sometimes, non-useful work is what is often responsible for environmental problems.[5]
